Over the last decade, regulators have accelerated their focus on vapor intrusion risk at hazardous cleanup sites. This has led to new cleanup standards, policies and guidance to evaluate potential risks, environmental investigation requirements for brownfield redevelopments, and the reopening of previously closed remedial actions. Recently, attention has turned from chronic to acute vapor intrusion risk. Although protection of human health is paramount, this recent focus has been plagued with concerns about the validity of the underlying science and a lack of comprehensive guidance from regulators on how to respond. This article explores the evolution of vapor intrusion regulation, particularly developments addressing acute risk, as well as trends in vapor intrusion- related litigation.
It is no secret that California has had appliance efficiency standards in place for some time now. And it is no secret that the California Energy Commission (“CEC”) has been responsible for crafting those standards. According to the CEC and the California State Legislature, however, compliance with those standards has been hit-or-miss. In 2011, the Legislature found that “significant quantities of appliances are sold and offered for sale in California that do not meet the state’s energy efficiency standards,” and the CEC itself has stated that nearly half of all regulated appliances are non-compliant, and that certain product categories are entirely non-compliant. The broad range of products covered by the CEC’s efficiency standards may be partly to blame for the lack of compliance, as manufacturers may not even realize their product must comply. For example, the efficiency standards encompass nearly every device with a rechargeable battery and that rechargeable battery system, meaning everything from cell phones to laptops to tablets to golf carts must be tested, certified and listed in the CEC’s database before being offered for sale in California.
